Light switch plates and outlet covers come in multiple gang options. The gang refers to a side-by side element in an electrical box. For example, in toggle switch plates, a gang represents the space where each switch goes. A 1-gang plate covers a box with one switch, while a 2-gang plate covers one with two switches. In a standard duplex outlet, a single-gang receptacle has a total of two outlets. That means a 2-gang wall plate covers an outlet box with two receptacles that contain two outlets each.
